  For example, as a horizontal shutter used in a sunroom, it responds to a request to open and close the opening / closing part by opening / closing only an arbitrary position of the opening surface, or to fully open to a plurality of opening surfaces. Thus, the applicant separately forms a shutter unit (may be referred to as a shutter unit, a door unit, etc.) in which a pair of panels having the same width are hinged to each other and the adjacent vertical shafts are connected to each other. A horizontal shutter has been proposed in which each vertical rod on the non-connected side of the shutter unit is suspended and supported between the upper and lower frames of the opening frame so that each shutter unit can be opened and closed independently. Since the vertical rods on the unconnected side are suspended and supported by the upper and lower frames, a gap is created between the lower end of the shutter unit and the lower frame. Therefore, when the shutter unit is extended and closed, the gap is closed to ensure airtightness or watertightness between the lower frame and the airtightness or watertightness. It is desirable to improve usability.

  The door lower end sealing device according to Patent Document 1 can seal the lower end of the door body in conjunction with the opening and closing operation of the door body, and can be applied to a sliding door, for example. However, if this is applied to the horizontal shutter, for example, the operation protrusions are positioned on one side of the panel and sequentially arranged so as to protrude from the panel end toward one side in the width direction (this arrangement). However, in this case, even if the bottom end of the panel can be sealed, the shutter unit should be a pair of panels with the same width. As a result of the hinge connection, when the shutter unit is extended, the operating protrusion protruding to one side of the hinge connection side is pressed by the other panel, and the lowered sealing beat comes into contact with the lower frame. Attempting to open and close the shutter unit with the shutter unit extended may result in an open / close failure due to the heavy opening / closing of the shutter unit. May cause damage. If the shutter unit is folded and sent in the longitudinal direction of the upper and lower frames and then stretched at the feed position, the opening and closing of the shutter unit can be opened and closed even though the opening / closing failure and the possibility of wear damage of the sealing beat can be eliminated. It is easier to extend in the extended state than to extend at the above-mentioned feed position, and in the folded state of the shutter unit, a pair of panels folded in a V shape from the upper and lower frames protrude in a cantilevered manner. Therefore, it is assumed that the user of the lateral pulling shutter performs the opening / closing operation in the extended state, and therefore, the above-mentioned patent document is applied to the horizontal pulling shutter using the shutter unit. It is not appropriate to apply the lower end sealing device 1 in order to leave the possibility of causing the opening / closing failure and wear damage of the sealing beat.

  The present invention will be described in more detail with reference to the example of the drawings. A is made of aluminum which can be suitably installed in an opening of a structure such as a solarium for outdoor space formed on a veranda or a wood deck. A horizontal shutter, B is a lower end sealing device. The horizontal shutter A includes a shutter unit 2 in which a pair of panels 21 having the same width are connected to each other by vertical hinges 23 connected to each other by hinges 24 to be freely extended and folded. Each of the vertical rods 23 on the unconnected side of the shutter unit 2 is suspended and supported between the upper and lower frames 1a and 1b of the opening frame so that each shutter unit 2 can be opened and closed independently. The stopping device B has a sealing beat 51 for contacting the lower frame of the opening frame at the lower end, and the lifting frame 5 housed in a downward opening groove having the same length as the panel width at the lower end of each panel, and the lower end of each panel of By disposing the operation protrusions 62 from the ends to the side in the panel width direction, the elevating frame 5 is lowered by the simultaneous pressing of the operation protrusions 62 at both ends when the shutter unit 2 is extended, and the sealing beat 51 is contacted with the lower frame. And a lifting mechanism 6 disposed above the lifting frame 5 in the downward opening groove so that the lifting frame 5 can be lifted by releasing the pressing of the operating protrusion 62 when the shutter unit 2 is folded and returned to the downward opening groove. The elevating mechanism 6 is arranged so as to be movable in the longitudinal direction of the downward opening groove so as to allow the movement of the elevating mechanism 6 in the longitudinal direction of the downward opening groove so as to allow the movement of the elevating mechanism 6 in the longitudinal direction. It is assumed that the lowering of the elevating frame 5 can be avoided by absorbing the pressing of the operating projections 62 located on the connecting side of the hinge 24 by the movement of the elevating mechanism 6. A.

  That is, the shutter unit 2 in the horizontal shutter A of this example is assembled into vertically long rectangles by upper and lower horizontal bars 22 and left and right vertical bars 23 made of aluminum extrusion material, and glass, synthetic resin, etc. By directly connecting a pair of panels 21 fitted with a transparent plate or a semi-transparent plate by the adjacent vertical gutters 23, that is, the escape side vertical gutters 23 by hinges 24 arranged at a plurality of positions on the upper and lower sides. 21 series expansion and V-shaped folding are made free. The shutter unit 2 has an upper suspension roller 26 disposed at the upper end and a swing roller 27 disposed at the lower end of the unconnected side vertical shaft 23 of each panel 21, and the upper suspension roller 26 and the swing roller 27 The upper and lower frames 1a and 1b of the opening frame are suspended and supported so as to be able to run in the longitudinal direction, and are opened and closed.

  The opening frame is provided with an upper frame 1a and a lower frame 1b in which guide rails 12 having a downward or upward opening are disposed for supporting the upper suspension of the shutter unit 2, and vertical frames at both ends in the width direction. The opening frame is such that the upper frame 1a and the lower frame 1b are arranged in a plane U shape so as to extend over the front and both sides of the sunroom, and each vertical frame is arranged at the building side end of the side surface. is there. At this time, the upper frame 1a and the lower frame 1b are arranged such that the front and side surfaces of the upper frame 1a and the lower frame 1b are provided by interposing a corner connecting member 11 having a ¼ circle roller passing rail so that the guide rails 12 are continuously connected. The shutter unit 2 is supported in a suspended manner by a predetermined number of front and side surfaces so as to close the planar U-shaped opening by its series expansion. . The shutter unit 2 is formed by connecting the pair of panels 21 having the same width to the hinge 24 and supporting the panel on the unconnected side vertical shaft 23, that is, the vertical shaft 23 positioned at both ends in the width direction of the shutter unit 2. Each of the shutter units 2 can be opened and closed independently, so that the horizontal shutter A can be folded in an arbitrary number of times at an arbitrary position in a plane U shape to allow people to enter and exit and to ventilate. I can do it. Further, at this time, the upper suspension roller 26 and the anti-roll roller 27 of the shutter unit 2 are arranged so as to be horizontally supported with respect to the vertical shaft 23 as shown in FIG. When the shutter unit 2 is in an expanded state and is manually fed toward the corner, for example, as shown in FIG. Passing through the roller passing rail, the upper frame 1a and the lower frame are sequentially advanced from the guide rails 12 of the upper frame 1a and the lower frame 1b orthogonal to the guide rails 12 of the other upper frame 1a and the lower frame 1b. 1b, the upper suspension roller 26 and the anti-rolling roller 27 at the rear end in the traveling direction pass through the corner connecting member 11 in the same manner, 1a and the guide rail 12 of the lower frame 1b, so that the horizontal shutter A of the present example can be opened and closed in an arbitrary number of positions, in addition to opening and closing an arbitrary number of sheets, for example, by folding one side and folding door pockets. Thus, by opening and closing the shutter unit 2 and folding it, it is possible to open and close a plurality of opening surfaces, in this example, the opening of the plane U-shaped three surfaces is fully opened. is there. In the figure, reference numeral 3 denotes a non-connected side vertical shaft of the shutter unit 2 that is movable in the longitudinal direction of the guide rail 12 by the upper suspension roller 26 and the anti-roll roller 27 and has a different direction at the corner when the shutter unit 2 is closed. The corner ridges arranged so as to close the space between 23 are shown.

  On the other hand, in the lower end sealing device B of this example provided with the elevating frame 5 and the elevating mechanism 6, the elevating frame 5 is provided with an upward opening groove having a C-shaped cross section on the upper surface and on the lower surface. The aluminum frame is provided with a beat receiving groove 13 composed of a pair of leg pieces, and the elevating frame 5 is formed by notching the lower ends of the vertical rods 23 on both sides of the panel frame assembly in one of the inner and outer directions. The housing 4 is arranged under the notch and the lower rod so as to extend over the entire length between the vertical rods 23 and accommodated in the downward opening groove of the housing 4, while the sealing beat 51 is placed in the beat receiving groove 13 on the lower surface. The mounting base portion is fitted, and the sealing beat 51 is disposed, for example, with the hollow contact portion projecting downward, and at this time, the lifting frame 5 of the housing 4 of this example is stored. Is the position before the position of the anti-roll roller 27 arranged at the lower end of the vertical rod 23. As performed in the displaced position, there as to adjust the positional relationship of the housing 4 to the lifting mechanism 6 and Futome roller 27.

  The elevating mechanism 6 also includes a pair of end slide rods 61 each having an operation projection 62 at one end in the longitudinal direction and a non-existence of the operation projections 62 in the pair of end slide rods 61 via compression springs 65 at both ends. A long leaf spring 66 for connecting the end portions on the arrangement side, and a middle portion in the longitudinal direction of the leaf spring 66, supporting a plurality of longitudinal portions of the lifting frame 5 and moving the lifting frame 5 up and down by its vertical movement. And a pair of end slide rods 61 via the compression springs 65 of the plate springs 66 are connected between the end slide rods 61 and the plate springs 66 at this time. The connecting rod 64 is interposed, and a compression spring 65 is compressively attached to the connecting rod 64.

  That is, the elevating mechanism 6 of this example has the end slide rod 61, the connecting rod 64 fitted with the compression spring 65, the plate spring 66, and the support member 67 of the plate spring 66 at one end so as to be symmetrical. It is assumed that the end slide rod 61 and the connecting rod 64 are disposed on the inner side of the end slide rod 61 and the leaf spring 66 is disposed therebetween, while the support 67 has the above-mentioned C-shaped upward opening groove. In the present example, two longitudinally intermediate positions are fitted or loosely fitted, so that the operation projections 62 projecting from the lower end of the panel 21 in the longitudinal direction, that is, the opposite ends of the panel 21 in the width direction are arranged. By pressing from both sides, the operating protrusion 62 enters the downward opening groove at the lower end of the panel 21 by the pressing dimension, in this case, into the housing 4, and the distance between the operating protrusions 62 is reduced. Accompanying this As a result of the plate spring 66 of the elevating mechanism 6 being bent downward by a reduction corresponding to the pressing dimension, the support 67 of the plate spring 66 is lowered and the elevating frame 5 is lowered, or the loose-fitting arrangement described above. In this case, the lift is lowered by the weight of the elevating frame 5, while if the pressing of the operating projection 62 is released, the distance between the operating projections 62 is increased to absorb the downward deflection of the leaf spring 66, and its support A tool 67 supports the lower surface of the opposed projecting piece defining the upward opening groove of the lifting frame 5 upward so as to lift the lifting frame 5, which is moved downwardly at the lower end of the panel 21, that is, in the housing 4. At this time, the compression spring 65 accumulates the urging force by the lowering of the elevating frame 5 while the elevating frame 5 is raised by the urging force when the operating projection 62 is released. Acts as follows.

  The lifting frame 5 and the lifting mechanism 6 of this example are integrated with each other by arranging a support 67 arranged on the leaf spring 66 in the upward opening groove of the lifting frame 5 in a loosely fitting manner. The elevating frame 5 and the elevating mechanism 6 are positioned and held by the small opening caps 7 which are attached to the lower opening groove of the lower end of the panel 21, in this case the housing 4 and arranged at both ends in the longitudinal direction of the downward opening groove. The operating protrusion 62 of the elevating mechanism 6 protrudes from the small cap 7 so as to protrude in the width direction side of the panel 21, and the elevating frame 5 can be moved up and down by the guidance of the small cap 7. The fore edge cap 7 is provided with an upper through hole for the operating projection 62 and a lower guide through hole for the elevating frame 5 in the vertical direction, and a downward opening groove at the lower end of the panel 21. In this case, the molded part is fixed to the housing 4 by an appropriate fixing means such as fitting or screwing, and the operating projection 62 is inserted into the upper through hole so that the width direction side of each panel 21 from the outer surface of the small cap 7 For example, an arrowhead-shaped guide member 52 arranged at the longitudinal end of the elevating frame 5 is received and arranged in the lower guide through-hole, while the positioning and holding of the elevating frame 5 is raised and lowered. Is possible.

  On the other hand, the operating projection 62 of this example that operates the lifting mechanism 6 is formed by a short bar having a length of, for example, about 0.5 to 1 cm. Thus, for example, about 5 mm, the tip portion of about 3 mm protrudes from the outer surface of the forehead cap 7 toward the side in the width direction of the panel 21, and this is performed. By pressing the protruding dimensions, The operating protrusion 62 is inserted into a downward opening groove, in this example, the upper through hole of the small cap 7, and the lifting mechanism 6 is operated.

  At this time, the operating protrusion 62 is, for example, a fin-shaped protrusion that is in contact with the rear edge of the upper through hole of the small cap 7 on the rear end, in this example, the end slide rod 61 side. The stopper 63 is arranged so that it is prevented from being removed by the stopper 63, and the position of the stopper 63 has entered the back side of the forehead cap 7 by, for example, several millimeters with the tip portion protruding. A downward opening, in this example, as an inward position of the housing 4, a sliding dimension is secured between the stopper 63 and the small cap 7, so that the downward opening groove of the lifting mechanism 6 is directed in the longitudinal direction. The movement is free. That is, the lifting mechanism 6 lowers the lifting frame 5 by the operation when the operating projections 62 at both ends thereof are simultaneously pressed, and lifts the lifting frame 5 by the reverse operation when the pressing is released. Depending on the positional relationship between the stopper 63 and the small cap 7, the elevating mechanism 6 can slide a small amount toward the one side until the stopper 63 of the operating protrusion 62 contacts the back surface of the small cap 7. As a result, the lifting mechanism 6 is not actuated by pressing one of the two operating projections 62 at both ends, so that the lifting frame 5 is incompletely actuated even if the lifting and lowering of the lifting frame 5 is suppressed or activated. As a result of suppressing the lowering range, the contact with the lower frame 1b of the sealing beat 51 arranged at the lower end of the elevating frame 5 is avoided. In the present example, the small dimension means that the distance between the lower ends of the opposing panels 21 when the shutter unit 2 is extended alone, in other words, between the vertical flanges 23 on the hinge 24 connecting side or between the small caps 7 of the housing 4. Accordingly, the lifting mechanism 6 is not operated by the pressing of the one operating projection 62, and the lowering of the lifting frame 5 is suppressed.

  Thus, by making the lifting mechanism 6 freely movable by a small size, particularly in the case of the horizontal shutter A using the shutter unit 2 in which a pair of panels 21 having the same width are connected to the hinge 24, the horizontal shutter A is arranged on the front surface, for example. When the horizontal shutter A is arranged, the shutter unit 2 is assembled at one end in the width direction of the front, and when the horizontal shutter A is arranged at the front and the side, the shutter unit 2 is assembled at one end in the width direction of the side. When the shutter unit 2 is fully closed or partially closed from the fully opened state of the opening that is folded, the shutter unit 2 can be expanded as if it were sequentially expanded and manually fed. 2, the operating projections 62 at the lower ends of the panels 21 located on the vertical rod 23 side of the hinge 24 connection press each other, and the lifting mechanism 6 moves the pressing dimension due to the pressing. As a result of the absorption, the lifting mechanism 6 of the shutter unit 2 is not operated, and therefore, the guide beat of the extended shutter unit 2 is avoided by preventing the sealing beat 51 from descending and coming into contact with the lower frame 1b. 12 Opening and closing operations including feeding movement in the longitudinal direction can be performed lightly and smoothly.

  On the other hand, in the horizontal shutter A of the present example, when all the shutter units 2 are extended and closed, the vertical projections 23 on the connecting side of the hinge 24 and the operating projections 62 on the adjacent vertical connecting rod 23 on the non-connecting side are mutually connected. Or at the end of the opening frame is pressed by the vertical frame or the corner ridge 3, the elevating mechanism 6 of all the shutter units 2 is operated and the elevating frame 5 is lowered, and each sealing beat When 51 comes into contact with the lower frame 1b, it is possible to seal the lower end of each panel 21 of the shutter unit 2 and the lower frame 1b to ensure airtightness or watertightness as the horizontal shutter A. .

  In this example, the lower frame 1b of the opening frame is provided with a guide rail 12 having an upward opening, and thus has a cross-sectional C-shape having a pair of partitioning strips facing the interior and exterior of the guide rail 12. The sealing beat 51 lower frame contact of the lowering of the elevating frame 5 is performed on the upper surface of one of the compartments of the lower frame 1b. At this time, in the lower frame 1b that contacts the sealing beat 51, in this example, the beat receiving groove 13 that is recessed in the longitudinal direction for receiving the sealing beat 51 is arranged on the upper surface of the compartment on the indoor side. As a result, the lower end 1b of the sealing beat 51 falls into the beat receiving groove 13 by the lowering of the elevating frame 5 so as to be fitted into the beat receiving groove 13 to allow airtightness or watertightness by sealing the sealing beat 51. The lower end sealing device B suitable as the horizontal pulling shutter A of the sunroom can be obtained while ensuring a high altitude.

  In the figure, reference numeral 25 denotes an airtight material of the full length in the longitudinal direction installed on the vertical shaft 23 of each panel 21, and 8 denotes an operation knob of the locking device for locking the shutter unit 2 to the upper and lower frames 1a, 1b when fully closed.

  Although the illustrated example is as described above, the horizontal shutter, the shutter unit, the upper and lower frames of the opening frame, the lifting frame, the sealing beat, the lifting mechanism, the operating protrusion, the end slide rod used as necessary, Each specific structure, shape, material, relationship, addition to these, etc. of the connecting rod, compression spring, leaf spring, engagement support, housing, fore cap, etc., are various forms unless they are contrary to the gist of the invention.
